Hi.
Is it the case with QImage frame-buffer too?
I mean by default MacOS X host VM uses Quartz2D frame-buffer but there is  
an experimental QImage frame-buffer support which can be used by trunk VM  
through '--rmode image' passed as additional argument to 'VirtualBox  
-startvm <vm name>' like:
VirtualBox -startvm Ubuntu --rmode image
